' Toa'ZZ-w'hom fitr/nay concern:

Be it known that l, JOHN B. DAVIS, a citizen of the United States, residing at Dayton, in the county of Montgomeryand State of Ohio, have invented certain newland useful Improvements in Power-Pumps for Measuring Oil and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it lappertains to makeand use the same, reference being had to the accompanying drawings, and to the letters and figL ures of 'reference marked thereon, which form a part of this specification.

. This invention relates to improvements in self-measuring'oil pumps. j i The objectof the invention is to provide. an oil pump which is adapted to be operated by power.

Among the principal advantages of a pump of this character is its several automatic features, among which may be mentioned means for/setting. the pump to discharge a certain .specific quantity of oil and at the termination of the operation, it is st'opped and the power automatically disconnected.

Other advantages ofl no less-importance are present, as will'hereinafter appear from the detailed description of the. invention tofolloW, taken in connection with the accompanying drawings, and as setforth in the claims.

In the drawings, Figure 1, is a front elevation of a power pump for measuring oil, the

Samev being constructed in Aaccordancewith my invention. Fig. 2, is a side elevation of Fig. 1,. Fig. 3, is a section on the line t-t of Figi 4. Fig. 4, is an enlarged detached view of the computing dial andv adjunctive delthrough the dialindeXing mechanism'. Fig.

9, is a detailed view of the consecutive counter operating in connection with the indicator'dial.- Fig. 10, is an enlarged detail View -of a portion of the mechanism for automatically releasing the manually-operative lever,-

on the line i of Fig. 5.

. ln a detailed description of the invention, similar `reference 'characters indicate corresponding parts.

The two cylinders 1 are mounted upon a base 2 and are inclosed at their upper ends by a cap 5 in which there is an opening for the outlet pipe; the cylinders so mounted are maintained between the base 2 and the cap 5 by tie rods 8. The rods 4 (Fig. 10) eXtending 'from the pistons within said cylinders are each connected to a cross head 4'L which moves on guide rods 3 secured between thecap 5 and head G. Connected 'to each of the cross heads 4"L is a pitman 9 lying upon the 'Ou'tsideof the pump cylinders andconnected at their lower ends with a crank wheel 10. Upon the shaft of these crank wheels there is a gear wheel 12 which engages a pinio'n 11 on the main power shaft 23 which is driven through the main driving pulley 13 through the clutch mechanism illustrated in Figs. 2

and 7. The -main driving pulley 13 runs loosely upon the shaft 23 and has clutch members 18 projected from the outer side or end of its hub 14, said outer end of said hub 'being provided with a recess 15 to receive a spring 19. On lthe outer end of the shaft 23 thereis a clutch 16 which is normally maintained out of an interlocking position with the hub 14 owing to the tensiony of the spring 19 being su'liicient to maintain-said hub mits inner position upon said` shaft 23. The clutch 16 is tight upon the end of the shaft 23 and has interlocking lugs 17 which engage the clutchy members 18 When the hub 14 is shifted into position, against the tension of the spring 19, to admit of such engagement.

Mounted loosely upon the shaft 23 adjacent to the hub 14 is a journal boss 22.0f the lever 7. Projecting from the side of said boss 22 is i a camA 21 which is designed to-ride into and out ofv a recess 2O in a collar 23L which isA Yfixed to a stationary part, for example, the bearing of the shaft 23. When the operating lever 7 is moved inwardly from the position shown in Fig. 2, to that shown in Fig. 1.0, the cam -projection 21 on the boss of said lever is caused to 'move out of the'recess 20 and thus forces the driving pulley-13 in engagement with the clutch 16,l the latter, `as before stated,` being tight upon the shaft of said pulley; the power is.thus transmitted to the crank Wheelv l and thence to' the' pistons Within the cylinders to move-said pistons-in o posite directions-.Within the cylinders.

e lever 7 moves in a slot ina guide plate 24 attached to the cap 5 at the upper 'ends of said cylinders and a latch is pivotedfat'31 to the u per side of said plate 24 and lies substantia y parallel with the slot in which the lever is moved; when the lever is moved against the latch 25 it 1s 'thrown .outwardly and the lever is thus' enabled Ato"linterlock with the latch as shown in Fig'. 10, The latch 2 5 is connected to an upright rody 28 through the means of a link 26 anda crank arm. 27, the crank armbeing fixed to the lower endl of the shaft 28. Surrounding a.

' portion of the shaft 28 is a coil Asprin '30 Which exertsa tension u on the shaft W chnormally maintams the atch 25 in the posision,' after which t tion shown in Fig.A 10. In operating 'the 1e'- ver to move it inwardly, the said lever moves.

against this springtene spring exerts its inuenceupon the shaft 28 to'return the latch to its normal position as in Fig. 10; this latch is automatically tripped from th'e osition shown in Fig. 10, to permit ofthe wit drawa'l the latch outwardly;

' of. the lever 7 to disengage the clutches at thel termination of each operation of thepump; the means for thus automatically.,tripping said lever will be presently described. The indicatingdial shown in Figs. 4 and 5 more clearly, comprises 'several parts whichA are housed Within a stationary circular plate' 33 having an'out-turned annular edge this plate is mounted above'the cylinders 'on aoWer bracket 29 which is securedto the'cap l '5,iand an upper bracket47which is secured to the head 6. 38 is a stationary ring .at-

tached to the plate'33 and 'having `'grad-ua,

tions on its `outer side Whijclll,designategal-k lons, there being one hundred of suchfgradu..

` ation marks, each of which indicates agallon of oil. Within thehousin thus form'edby the stationa plate 33am' dial ring v3 8; is a ratchetwhee '36 having teeth corresponding' in number to the 'graduation 4marks on vthe @dial ring 38; this ratchet wheelsfxedto a disk 37 which has in its inner side a C'QD'en- -I ,iumber to t v '38, and the teethon the wheel 36; these- ,tricline of a ert'n'res 46 which correspond in e graduationv marks on the ring 'arta to-Witftheratchet Wheel 36and the Sk4137. rotate -in unison upon -ay common "shaft Which penetrates the axis of ythcplate 33 and has a proper bearing therein. On the inner sidecf the disk 37 there is a concentric row of pins 40, the number ofsuch pins being half-that of the number of the graduatlons' on the dial ring 38 further reference will b e' made'to these pins 40. The pointer 44 ismounted upon a disk lwhich lies' lushwith' the dial fring,l said diskbeing. loose upon a stub Shaft, Benetratingtlle; disk-53. in almesurvie .-trolled pill. 45 Which'is adapted to be inserted 'infany'oue of the apertures 46 by rotating the dial '5B-With the pointer, the

pointer being' movable 'from the zero position andfl. It will be understoodI that th'edi'sk 53 with the dial'pointer 44v is moved to the right-as shown in Fig. f4 to index the pointer 44 at the proper point fon the dial ri 38, and

that owing to the engagement of sai disk '53 with the-disk 36 through the pin 45in aper'#` ture 46,-the'said disk 53 with the.pointer is the left' from the'index position, see Fig. 4.

The ratchet wheel 36 1s moved step by step from either. of the piston rodsthroughthe following interveningmechanism?` `32 is .a

#ratchety plawl. engaging'-the teeth of the y leel' 36; this' pawl 82 is .carried upon i e ratchet .W an arm 35 lying within the. housing formed of the' plates-33 and 38.

This arm 35 is com" given' a reverse movementl or a movement to:

nected with a similar arm 34 through an in- 'v tervening hub shogvnvirr dotted lines in Fig.

3, said hubhavi fa' bearing in a boss 56 ex tendi' von each'side of the stationary plate 331. lf e` outer 'arm 34lies in the path of a trip arm"V 50' whichisattached to one of the cross-heads only-see 2,j andwvhen the cross head .4 is elevated byits specific piston rod, the' trip arm'50 e lages the arm 34 and impartslmovement to t e pawl-carryingar11-- the r.'35Qsufli'ci'ent t'o cause a movement of AvI'ttchet wheel 36 to' theextent of'one tooth l or to the extent of ai gallon of oil.I At this 'pOl'tt'Wll be understood, thateacli of the cylinders 1 has a'capacity for pumping a half. ".gallo' of oil in each o eration and that a dis 'charge of each cylin er is necessary to disl pense al gallon of oil; it therefore will be' seen'that the operation of one'cylinder alone need Befreeorded on the dial and that such operation has the eiiect of moving the.

ratchet Wheel 36 and therewith the. dlsk 37 the extent of one tooth or one gallon of oil,"f.

the combined quantity d'ispensedin a single a series of pins 40 on its inner side before rel ferred; to'; these pinsin therotation of; the 'disk 37 inthe mannerjust described, will en-f 'gage a toothed Wheell 43' on the shaft of a zonsecutive counter '42 housed within an off- 'set 42"" on a side ofthe stationary plate 33,

vsaid olfset having'a sight opening 52tlirouvh' which theconsecutive counter v42 is lvisib e. Asv before stated, each of the pins 40'stand,

for two gallons of oil, while each of the teeth on the ratchet wheel 36, vand the apertures 46 in the disk 37 stand for one gallon ofloil, thereforcnhen each of the pini: 4() trip the toothed wheel 43, two gallons ol oil is added upon the counter 42. A

The arm 34, when released by the trip arm 50 is controlled by a spring 4S which maintains said arm in its operative position by stopping it against a stop-piece 48*L attached to the stationary plate 33.

`Having described my invention, I will detail briefly an operation thereof.

Looking at Fig. 4, to dispense .a quantity of oil, say ten gallons, the pin 45 Figs. 4 and 3, is withdrawn from its zero engagement with the disk -37 and is moyed witl1'the pointer to a position which admitsof said pin reentering the aperture 46 in the disk37, in a line with Fig. 1() on the dial ring 3S. .Thedial pointer is then indexed for itshackward;

movement'to zero. The lever iis then moved inwardly from the position shown in Fig. 2V to that shown in' Fig. 10, and is locked in such position by the latch 25; by this operation, the main driving wheel13 is caused to engage the clutch, Fig. 7, and the machine is started. One or the other of' theI pump cylinders is caused to `Iirst discharge its half gallon of oil, after which the next pump cylinder is caused 'to make a similar discharge; the cross head 4 of one or the other piston rod is caused to trip the arm 34 by engagement of the trip arm 5,() therewith, said trip arm 50 being attached to the said cross head. ,This operation is repeated and the result is the ratchet 'wheel 3.6

. and disk 37 are uniformly moved step by step,

measuring a gallon at a time on the dial 38, until the pointer 44 1s returned to 1ts zero position, at wlnch tune. said pointer engages the arm 47 on the upper end ci shaft'28 and rocks said shaft suiliciently to remove the latch 25 from the position shown in Fig. 10 the lever f 2. In a power 7 is then moved outward by the spring 55 to l detach the clutch members.
